1. who says it hasn't?
2. most of the vul code is C, which is obviously much harder to harden, and the Rust Evangelism Strike Force loves to pretend that C++ is the same as C, so no matter the improvements to C++, they will just point at C.
3. I think many simply didn't know about these hardening modes, MSVC has had this for 10-15 years, but I still encounter people who don't know about it..somehow.
It isn't just the dominate group, it is everyone.
So simplifying, if you have only 2 groups, one being 30% and the other 70% of the population, it would at first appear the 70% group has an advantage for finding jobs, but in reality they do not, as while they are favored at 70% of jobs, they are also competing against an equivalently larger group of people.
Anyway the implementation of racial preferences in college applications, and DEI has led to a system that systematical favors certain groups, and gaslighting that somehow this isn't the case.
I don't support Trump but liberals denying this reality, along with various other incredibly stupid woke positions, has led to the current situation, where we have a complete and utter imbecile running the country, because hey, at least he doesn't deny reality in regards DIE/social issues.
